Hi, everybody, thanks a lot for the comments and info. I can confirm that Behringer U-Phoria UMC22 is working flawlessly out-of-the-box in a regular Arch installation. (And just in case of interest, also the old Mbox 1/classic from digidesign with FocusRite pre-amps, provided it has the last firmware update.) I'm trying to update the info at: https://www.alsa-project.org/wiki/Matrix:Main , but can't find how to edit page or create an account... Let me know if there's something specific I should do. Best regards and thanks a lot again!
